LACING MACHINE.

r Application filed July 19, 1920. Serial No. 397,403.

To all whom it may concern:

Be it known that I, HERBERT E. ENsLIN,

a citizen of the United States residing at Beverly, 1n the county of Essex and Stateof Massachusetts, have invented certain new and useful Improvements in Lacing Machines; and I do hereby declare the followmake and use the same.

The invention relates to; machines for lacing shoe uppers, in which one or more holes of an upper.

The object of the invention is to-provide. for the ready and convenient. removal and insertion of the looper spindles and for the accurate and uniform positioning of the spindles in their carriers. To this end each spindle is provided with a radial projection which is confined between the end of the carrier and a retainer, andthus' determines and fixes the endwise position of the spindle. The retainer is preferably mounted so that it may be moved out of its retaining position in front of the projection and thus permit the removal or insertion of the spindle. The circumferential position of the spindle may be, and preferably-is. fixed and determined by a lip on the end of the spindle carrier arranged to register with and engage a flattened or eccentric surface on the spindle. p

The invention will be readily understood from an inspection of the accompanying drawings and the following detailed description of the mechanism illustrated therein.

In the drawings Fig. 1 is a front elevation showing the support in which the looper spindles and cooperating looper fingers are mounted, Fig. 2 is a side elevation of the same, and Fig. 3 is a sectional detail. on an enlarged scale, the section being taken on a line passing vertically through one of the looper spindles.

In the drawings the invention is shownas embodied in an upper lacing machine having substantially the construction and mode of operationof the machine shown and described in Patents No. 1,030,547 and 1,030,573,June 25, 1912. In this machine a series of loops of lacing cord is held by a series of looper spindles 2. and a coopcrating series of looper fingers 4:. in position to be passed through the eyelet holes of anupper. The spindles aremounted in spindle carriers 6, which are in turn mounted tooscillate in blocks 8, laterally adjust able in a vertically movable support 10. lnthe construction shown-each spindle carrier is provided with a socket for receiving the inner end'of the corresponding spindle.

jecting collar or flange 12 arranged to engage the outer end of the carrier and thus determine the lengthwise position of the spindle. The flange is slabbed off on the lower side to form afiat eccentric surface 14:, which "is arranged to beengaged by a lip 16 projecting from the end ofthe carrier, and acting'to determine the circumferential position'of the spindle and to firmly hold it from turning within its socket. The spindles are firmly held in position against lengthwise movement within their sockets by a retainer bar 18, arranged to engage the front faces of the flanges 12, and to confine the flanges between the bar and the ends of the carriers 6.

moved into and out of active position when one or more of the spindles is to be removed,

inserted or "changed, it is provided, with tion to the machine of the patents above referred to it will be understood that this 3 The spindle is provided with a radially prospindles are arranged to pass a series of. loops of lacing cord through the eyelet In order that the bar may be conveniently and quickly construction and arrangementis not. essential to the broader features of the invention and may bevaried or modified as found desirable' or best suited tov the construction of the machine "in which it is'to be embodied.

What is claimed is:

1. A. lacing machine having, in combina-' tion, a spindle carrier provided with a socket, a looper spindle fittingtherein provided with a radial projection for engaging the end of the carrier, and a retainer for engaging the outer face of the projection.

2. A lacing machine having, in combina tion, a spindle carrier provided with a socket, a looper spindle fitting therein provided with a radial projection for positioning it lengthwise, and a retainer movable into and out of position in front of the projection.

3, A lacing machine having, in combination, aspindle carrier provided with a socket, a looper spindle fitted. therein pro vided with a radial projection for determining the lengthwise position of the spindle, a retainer movable into and out of position in front of the projection, and means for fixing the circumferential position of the spindle.

4-. A lacing machine having, in combination, a spindle carrier provided with a socket, a looper spindle provided with a flange having an eccentric surface, a lip on the carrier for engaging the eccentric surface to determine the circumferential posit-ion of the spindle in the carrier, and a retainer for engaging the outer face of the flange to determine the lengthwise position of the spindle in the carrier.

5. A lacing machine having, in combination, a spindle carrier provided with a socket and having a lip at its outer end, a looper spindle fitting therein provided with a flange having an eccentric surface for engaging the lip, and a retainer movable into and out of position in front of the flange.

6. A lacing machine having, in combination, a series of spindle carriers, each provided with a socket, looper spindles fitted therein, each provided with a radial pr0jection, and a retainer movable into and out of position in front of the series of projections.

7. A lacing machine having, in combination, a series of spindle carriers each provided with a socket, a support in which the carriers are laterally adjustable, looper spindles fitting within the sockets in the carriers, each provided with a radial projection, and a retainer bar mounted on the support for movement into and out of position in front of the radial projections.

8. A lacing machine having, in combina tion, a series of spindle carriers, each pro vided with a socket, a support in which the carriers are laterally adjustable, looper spindles fitting within the sockets in the carriers, and each provided with a flange having an eccentric surface therein, lips on the carriers registering with the eccentric surfaces on the flanges, and a retainer bar mounted on the support for movement into and out of position in front of the flanges.
